> Subject: [PATCH v2 0/4] net/mlx5: support send scheduling for ConnectX-7
> 
> Since the ConnectX-6DX the send scheduling capability is provided.
> An application can register the dynamic field and dynamic flags in mbuf for
> timestamp and specify the desired moment of time the packet should sent.
> 
> The send scheduling feature over ConnectX-6DX uses the complicated
> infrastructure with reference Clock Queue and inter-queue synchronizing
> operations. Since ConnectX-7 the new wait descriptor format is introduced
> where the timestamp can be promoted to hardware directly.
> The patchset adds support for this new hardware option in PMD.
